A light-emitting material according to the present invention is a film-forming material used for film formation by a liquid-phase method and is a light-emitting material for forming a light-emitting layer. The light-emitting material, which is a solution, includes a plurality of film-forming components and a solvent for dissolving the film-forming components. The ratio of each of the film-forming components in the light-emitting layer to be formed is different, and each of the film-forming components is prepared with a ratio substantially equal to the desired ratio and is dissolved in the solvent. Saturated concentrations of the film-forming components in the solution at a predetermined temperature are different from each other corresponding to the difference in the desired ratio. |
